Good to know! I read these comments in the specification:
type Socket_Type is private;
-- Sockets are used to implement a reliable bi-directional
point-to-point,
-- stream-based connections between hosts.
and just assumed datagram sockets were not supported. That's what I get
for reading comments, I guess! But now I also see:
type Mode_Type is (Socket_Stream, Socket_Datagram);
-- Stream sockets provide connection-oriented byte streams. Datagram
-- sockets support unreliable connectionless message based
communication.
So I think I'm good to go.
Thanks.
Peter
